Aryx do you know who can take a look at this until ahal is back?

Flags: needinfo?(aryx.bugmail)

This test framework issue only affects macOS opt. Joel, any idea why?

Flags: needinfo?(aryx.bugmail)

I looked around at a a few errors and a few files of the test and support files, there is nothing OS specific that I see. Likewise the manifest doesn't seem to indicate tests that only run on a specific OS.

A few thoughts:

  1. the OS integration code for clicking and switching focus is glitchy on OSX vs other platforms and these tests expose that
  2. maybe there is a skipped test on OSX which on other platforms sets the browser up for success
  3. can we reproduce this on try? If we can, can we disable a test or two and see the problem go away or does it move elsewhere?

Looks like the issue is confined to browser/base/content/test/general/browser_search_discovery.js, though I can't make sense of the log. Kris, I found your name in annotate for that test, do you have any ideas on what's happening in this log?

Or could you help us redirect to someone else? Thanks!

I haven't done anything significant with browser_search_discovery.js. My name is only in the log because it was hit by a scripted rewrite that I landed.

That said, the issue is with the browser_save_video_frame.js test which runs before browser_search_discovery.js in the same session. The test completes before some async transfer code completes, and tries to call a callback after the test has completed, at which point the test harness functions have been cleared.

Excellent, thanks for investigating Kris.

<game show host>Mike Conley come on down!</game show host>

Found your name in annotate for browser_save_video_frame.js. Given :kmag's comment would you be able to help fix or help find someone to fix this intermittent? Thanks in advance!

I investigated this as I thought that failure was due to the patches in my try run.

Awesome, thanks Florian!
